Quick Note Before You Begin

Before applying any fixes, make sure to check these prerequisites:

  • Verify System Compatibility: Ensure your PC meets the minimum requirements for PCSX2, including a decent processor and graphics capability.
  • Update Windows 11: Running the latest Windows updates can fix compatibility issues that cause runtime errors.
  • Close Other Programs: Sometimes, background applications interfere with PCSX2. Close unnecessary apps before running the emulator.
  • Run as Administrator: Right-click the PCSX2 icon and select Run as administrator to give the program necessary permissions.

Step 1: Update DirectX and Microsoft Visual C++ Redistributables

PCSX2 relies on DirectX and Microsoft Visual C++ packages to run properly. If these are outdated or corrupted, runtime errors may occur.

How to update:

  1. Press Windows + S, type Check for updates, and open the Windows Update settings.
  2. Click Check for updates and install all available updates.
  3. Visit the official Microsoft Visual C++ Redistributables page and download the latest versions (both x86 and x64).
  4. Download and install the latest DirectX End-User Runtime from the Microsoft website.
  5. Restart your PC to apply changes.

Why this matters: Updating these components ensures PCSX2 has the necessary system libraries to function correctly.

Step 2: Install or Reinstall PCSX2 Properly

Sometimes the runtime error happens due to an incomplete or corrupted PCSX2 installation. Reinstalling can fix missing or damaged files.

How to do it:

  1. Press Windows + R, type appwiz.cpl, and press Enter to open Programs and Features.
  2. Find PCSX2 in the list, select it, and click Uninstall.
  3. Go to the official PCSX2 website (https://pcsx2.net/) and download the latest stable version of the emulator.
  4. Run the installer and follow the on-screen instructions carefully.
  5. After installation, run PCSX2 as administrator.

Why reinstalling helps: This ensures all necessary files and settings are properly configured and fresh.

Step 3: Check Compatibility Mode Settings

Running PCSX2 in an incompatible mode can cause runtime errors. Windows 11 may sometimes try to run older programs in compatibility mode unnecessarily.

Steps to disable compatibility mode:

  1. Right-click the PCSX2 shortcut or pcsx2.exe file.
  2. Select Properties and go to the Compatibility tab.
  3. Uncheck Run this program in compatibility mode for: if it is checked.
  4. Click Apply and then OK.
  5. Try launching PCSX2 again.

Reason: Compatibility mode is useful for very old programs, but it can sometimes interfere with newer software on Windows 11.

Step 4: Disable Antivirus or Add Exceptions

Some antivirus or security software may block PCSX2 files, causing runtime errors. Temporarily disabling antivirus or adding PCSX2 as an exception can help.

How to do this safely:

  1. Open your antivirus or security program.
  2. Look for a setting called Exclusions, Exceptions, or Whitelist.
  3. Add the PCSX2 installation folder and pcsx2.exe to this list.
  4. Alternatively, disable the antivirus temporarily just to test if PCSX2 runs without errors.
  5. Remember to re-enable antivirus after testing.

Why: Security software might mistakenly identify PCSX2 as a threat and block its execution.

Step 5: Update Graphics Drivers

PCSX2 requires up-to-date graphics drivers to emulate games properly. Outdated or corrupted drivers can cause crashes and runtime errors.

How to update your graphics drivers:

  1. Press Windows + X and select Device Manager.
  2. Expand Display adapters.
  3. Right-click your graphics card and select Update driver.
  4. Choose Search automatically for updated driver software.
  5. If no updates are found, visit your GPU manufacturer’s website (NVIDIA, AMD, Intel) to download the latest drivers.
  6. Install the drivers and restart your PC.

Note: Updated drivers improve performance and compatibility with emulators like PCSX2.

Alternative Advanced Fix: Run PCSX2 in Clean Boot Mode

If none of the above steps work, a clean boot can help identify if other software is causing the conflict.

How to perform a clean boot:

  1. Press Windows + R, type msconfig, and press Enter.
  2. In the System Configuration window, go to the Services tab.
  3. Check Hide all Microsoft services, then click Disable all.
  4. Switch to the Startup tab and click Open Task Manager.
  5. Disable all startup items in Task Manager.
  6. Close Task Manager and click OK in System Configuration.
  7. Restart your PC and try running PCSX2.

Why this helps: A clean boot starts Windows with minimal drivers and programs, making it easier to spot software conflicts.
